Prompt to add `_#` when renaming a function with a name that's already taken

[loadlibraryninja]

What is the feature you'd like to have?

When renaming a function with a name that's already defined, can it behave just like when renaming a variable the same name where it suggest appending _1 to the end as the default action?

Is your feature request related to a problem?
Me hitting enter too fast 😊

Are any alternative solutions acceptable?
Manually adding the _1
