Adding separator to versioning

Anyone know a way to add . seperators to versioning example I have this file.
Any idea how to make with Regex, I put this one to match _V\d{1}\d{1}\d{1} but I cannot seem to find the complete replace string



NL_XXX_XXX_V114
I want to rename it to
NL_XXX_XXX_V1.1.4

For the example, your "Match" and "Replace" can be like...
(.+_V\d)(\d)(\d)$
\1.\2.\3
