Multi episode naming/missing

I am not sure where this falls into but it will save me alot of manual renaming and missing.

how it works now:

EX: Bones 04x01-02 The Yanks In The UK.avi suggests to rename to Bones 04x01 The Yanks In The UK(1).avi and leaves me the second ep missing.

How I would like it to work:

Bones 04x01-02 The Yanks In The UK.avi it says YAY!!! you have both eps and not show it as missing the second part

on a un related note this is the most amazing app i have ever come across

This is already supported.

Expand the series you're looking at, select the season, and press Edit. Then add a merge rule for the episodes you want merged together.

Yep, you edit the season on the "My Shows" tab, and add a rule to Merge the episodes into one file. TVRename doesn't automatically detect/guess which files are double episodes.
