Is it possible to do search replace with partially underlined strings?

Is it possible to do a search and replace of partially formatted string that looks like this?

05010700.2

replace with

05010700.2X

I know this seems like a really simple task but I've been having difficultly with it because it's only partially underlined.

I'm not sure I follow what you're trying to do.

Do you want to replace '0700.2' with '0070.2X'? A simply Find and Replace works fine for me.

Find What 0070.2
Replace With 0070.2X
