Remove BP attachment

Hi!

We have some BPs with a lot of files attached to it, and most of then become useless after some time. Our customer asked if it would be possible to remove it from the BP records.

I have configured in our DEV instance a record editor form and i was able to remove all the unpublished attachments from the BP records as request, but it'll be a big manual work in production, as we need to open each record to remove the attachments.

Anyone know another way to do that? Like a "bulk edit" to remove attachments?

Thanks!
