How to readvalue<type> with 2 of the same types?

I’m trying to make a system that pans around the screen when I click and drag. Doing so requires me to have the mouse position and the delta position, both of which return vector2. In code when trying to use ReadValue(); is there a way to specify which vector 2 value I’m looking for? Seems a little wrong to not have more options than just the first that comes up.

I would record the pointer position each frame, and just use the difference in that to calculate your delta.
