This is a small enhancement to the AUTOINC* feature that auto-increments numbers for automatic topic creation.

Currently any prefix can be used, such as PrjAUTOINC001 to create Prj001, Prj002, Prj003, etc.

If the new topic or existing topics have a suffix, auto-increments no longer works as expected. For example, I'd like to have Prj001Foo, Prj002Bar, Prj003Moo, etc, where the suffix is specified at topic creation time, such as PrjAUTOINC001Foo .

This enhancement allows arbitrary suffix after the number.


  • Create topic using name PrjAUTOINC001FirstProject -- results in topic Prj001FirstProject
  • Create topic using name PrjAUTOINC001 -- results in topic Prj002
  • Create topic using name PrjAUTOINC001SomeSuffix -- results in topic Prj003SomeSuffix
