Is it possible to delete fonts in EngageOne Designer Version 6

Products affected:  Doc1 Designer
Versions affected: all 6.x
Version 6.x of EngageOne Designer does not permit the user to delete fonts from the font library once they have been imported into the repository (even if they are unused).

A workaround would be to remove all references to the font no longer required, export a snapshot of the publication\project strand, and import this into a clean repository.
