Effects for modifying Rolls [Feature Request]

What would be great would be if the effects that could be added to features, could include effects to modify rolls on actor with the effect, or damage rolls on the target of the actor with the effect.

A possible alternative would be hooks during the rolls such as preRoll and updateRoll for all roll types so that external modules can modify these rolls, if you don't wish to allow for those features in the system itself.

Why, well features like this:

Life Cleric's - Disciple of Life: Starting at 1st level, your healing spells are more effective. Whenever you use a spell of 1st level or higher to restore hit points to a creature, the creature regains additional hit points equal to 2 + the spell's level.

Elemental Adept - When you gain this feat, choose one of the following damage types: acid, cold, fire, lightning, or thunder. Spells you cast ignore resistance to damage of the chosen type. In addition, when you roll damage for a spell you cast that deals damage of that type, you can treat any 1 on a damage die as a 2.

At present the only workable solution seems to be to make custom copies of the spells on actors with those features to allow them to use a different roll, this is time consuming, and cumbersome to have to do every single time a player gets one of these. There are probably other features that do similar that I am unfamiliar with, these are just two very obvious examples.

I understand Elemental Adept is not SRD, and I am not suggesting adding it, only that an option can be added for those people who own the rights to use PHB material that want to add the feat themselves so they can make it work.
