This thread has a good discussion of XC logging and definitions.

http://www.airlinepilotforums.com/as...ulti-time.html

You refer to 135 and 61 XC, but actually there are three different definitions for XC in 61 (see my post in the other thread). Two of those definitions are specific to aeronautical experience for ratings, the other is the "general" definition which would apply to 135.

It's perfectly OK and expected to use the general definition (any flight with a landing at point B) for logging XC once you have all of your ratings.

But depending on how much TT and XC time you have I might not bother going back and changing your logbook, unless you are short on XC for some airline's minimums. XC is usually not a big competitive factor (although you will need to have a minimum amount for many regionals).
