Can .idx and .sub files with same name as video be renamed?

hi, i'm a new user to tv rename and so far it looks like a great application to have. I read the user guide and searched the forum for the following query.
Here is an example of what i'm trying to do:

Xfiles Season 1

my files are in the format
XFDISC1.Title1.avi
XFDISC1.Title1.idx
XFDISC1.Title1.sub
XFDISC1.Title2.avi
XFDISC1.Title2.idx
XFDISC1.Title2.sub and so on

so i added .sub and .idx to the other file extensions field and then selected the rename function but only the avi file gets renamed and not the idx and sub files.
Is there something i'm missing or is this not supported?

Please help, it would save me so much hassle with all of my ripped tv shows as i need the subtitles since i'm hard of hearing.

There should be a button in either "Edit Show" or Preferences where you can enable Move files with same name..

This feature has been in TVRename for a while, but I noticed a couple of weeks ago that it wasn't working (and possibly hasn't been for a while). In Preferences>Files and Folders, there is an option called "Copy/Move files with same base name as video", that is supposed to do exactly what you want.

Making this work again is on my list of bugs to fix this week.
