Better fan control for high temp materials like ASA

Is your feature request related to a problem?

I have been printing ASA/ASA-CF a lot and as you might know, you should never use 100% cooling or you will be printing foam, you still wanna have a decent bridging.
Still, OrcaSlicer lacks that fan management, so for example, this is all fan related settings I can see.

Yet, there is no way to set bridge to 100% cooling, 33% cooling will look like crappy haha
I mean, it will slow down but the cooling speed isn't optimized.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

PrusaSlicer on the other hand does allow you to set bridge ONLY to 100% even so I didn't manage to get that to work, that is not the point of this ticket.
It would be awesome if OrcaSlicer has this extra fan setting and working hahaha

Can we please get independent fan speed for bridges implemented? I am printing high speed TPU and Orcaslicer no good for this. It is not usable for high speed TPU. Setting a high fan speed for overhangs pushes the filament all the way down to whatever is below it. Bridge fan speed should not be connected to the overhang fan speed. Overhangs have an underlying layer of filament to rest against. Bridges do not. They are COMPLETELY unrelated. There are other issues directly related to the limited ability to handle bridges in orca slicer. IMHO this is the biggest pitfall of this software.

I'll have a pretty good looking temperature test for TPU until the bridge. Then it all goes to the toilet as it gets shoved down by the fan.

Second the above points. Orca has very detailed settings for overhang speed, but fan speed can't be controlled at the same level as Prusa Slicer. I find myself missing this feature quite a lot, especially with high speed profiles.

Adding on to this. We need independent fan speeds for internal and external bridges. as well as overhangs.

Figure I might as well add that support interface fan speed would be fantastic to weaken the bond between the part and the support without an excessive gap. I think SuperSlicer is the best reference to aim for with all this. Pretty much any extrusion type can have it's fan speed overridden and the fan speed behaviour is summarised in text form below. Only thing it misses is a more fine tuned overhang setting that Prusa has.

This feature (fan speed for support interface) has already been implemented.

Apologies. Don't know how I missed that.
