Feature request for YTD and All Time Elevation

[snicker]

Thanks for the sensors! This integration has been working great for me for over a year. I have been using it to set up goal tracking for distance inside my HA instance. However, with the upcoming Zwift Wahoo Climbing Challenge I was thinking about setting up something similar for tracking how much elevation I've tracked since a certain date/starting elevation. Is this something that is accessible and able to be exposed?

I know it's possible to get it for each activity, so I may end up just automating an addition to a text sensor or something if it's not possible to expose.
