Is it possible to automatically apply function signatures from a gdt based on fidb application?

[lightspot21]

Suppose I can generate a .fidb file mapping function hashes to names, as well as a .gdt containing data types and signatures (as in typed arguments, return type and calling convention) of those same functions.

If I apply the .fidb, will Ghidra apply the corresponding signatures (say matched by function name) by itself from the gdt so as to correct the decompiler's output, or should I make a script for this?

I found an option called "Apply Function Data Types" when you right click an archive in Data Type Manager.
