Automatically propagate types in IDA pro when variables are assigned?

Question

Let's say I have this code in the decompiler of IDA pro:

var1 = var2; 

And assume the type of var1 is X (for example X could be char array with size 5). Is there anyway that I can tell IDA that whenever you see such assignments, change the type of var2 to X as well?

Considering that var1 is type X, then obviously var2 should be type X as well, but right now I have to manually change the type every time… The problem is this is happening inside a large function thousands of times and I can't manually change every time, I need to somehow force IDA to do it. But how?

HexRaysPyTools has this feature, which it calls "recasting" (SHIFT-L, SHIFT-R). It's generally an excellent piece of software and I recommend it.
