multiline regex

As far as I understand, current regex logic applies the regex to each line of text separately.
Can you please allow the regex to search multiple lines at once?

The use case for it is searching for multiple mods from a pool of mods.
So that something like:
"((mod1|mod2|mod3|mod4|mod5).*){3}" would highlight an item that has any 3 of the 5 mods I am looking for
