Consolidating text types

Hi !
I’m trying to consolidate the mess of text types in my file.These are spread across all the various system families, text note types and schedules. The Sofistik Bimtools plugin for example does not consolidate the types, rather it just modifies them all. I want to select all my text types to be replaced by a single one, and then purge the substituted ones from the document entirely.

Anyone got an idea how to tackle this ?
