[galaxy-dev] Remove entry from Tool Data Table using via Data Manager

Hello, I'm working on galaxy integration for an MLST tool called MentaLiST: https://github.com/WGS-TB/MentaLiST/tree/master/galaxy I've created data managers that create kmer databases and store their locations in a Tool Data Table. I'd like to allow users to remove entries from the Tool Data Table. Has anyone seen a Data Manager that provides that functionality? Should I create separate data managers for add and remove functionality, or can it be integrated into one? Thanks, Dan
