How to automate function return-type casting based on its sole input parameter?

[michael-g]

I'm reviewing some multi-threaded code which makes use of thread-local storage. I would like to be able to update all the instances in the Decompiler view where the call to __tls_get_addr is passed one memory address in particular, such that just these results are cast to a custom struct pointer. Doing this manually is theoretically possible, but there has to be another way.

Has this functionality already been developed for Ghidra? If not, what approach should I take, and is there any similar prior art I could use as a crib?
