I'm having a hard time finding an option to remove attachments using Butler that start with a specific URL. I'm using Butler that copies a card from one board to another. The card in the primary board has PDF attachment that gets auto attached using Zapier hence dynamic URLs are being generated for the attachments. The URLs start with https://trello-attachments.s3.amazonaws.com/abcdefgh/mypdf.pdf where abcdef is a very long and unpredictable aphanumeric character.
Now after the card is copied to another secondary board and linked with the primary card, I wish to remove the PDF attachment from the copied card. Under butler I could find the option to "remove link" under -/+ tab. However, I cannot select the specific attachment nor I can enter wildcard URLs. (https://trello-attachments.s3.amazonaws.com/)
So my question is, there a way to remove attachments in the copied card whose URLs are auto assigned by Trello itself?
