Mark-up style mass delete

[piton]

Hi, we have several files in ArchiCAD16 that inherited 100s of mark-up styles from various places.

Can I somehow mass-delete them?
The Mark-up style dialog only allows deletion one-by one.

Thanks,
BP

Totally support you! This attribute (Mark-up Styles) underdone definitely. I wish that the dev.team thinks about it, for example, including this one to 'Attribute Manager".
