Request for a way to delete a few obsolete strings from Qt Linguist

[KMKT]

Hello,

While I know how to remove ALL obsolete strings with lupdate -noobsolete, I think it would be convenient to have a way in Qt Linguist to delete specific strings, for example by pressing <Del> (or by right clicking on the string with choice "Delete" in a popup menu).
If several TS files are opened, deleting one string would delete all the obsolete translations in all the opened files.

Indeed, I have several strings that were translated then commented out temporarily. If I update the TS files with option -noobsolete, I will lose those translations for when I want to bring them back.
Currently, my only solution is to open all my TS files (in all languages) with a text editor and search for the obsolete source text I spotted in QtLinguist, check that is really is the proper text, and delete all its section from "<message>" to "</message>".

Thanks for your understanding!
