Describe the feature

It will be nice to add Custom Numer Tag to split big and long numbers with commas.
Ex. 7,777,777 insteed of 7777777.

Describe the implementation

Just separate numbers with commas :D

Would be cool to just have a setting to decide what kind of separator you want - none, comma, dots - and that setting affect all the non-short numbers for the tags (and idk where else it would be applicable)
