Is a way to add an attachment field to Assist?

[Steve Fitzgerald]

Is there any way to add an attachment field to Assist tickets (through Slack)? Or add form? I'm assuming there isn't since I don't see an option for it during my testing, but I thought I'd ask just in case.

I too would like to know if this is possible. It is a pain to have users submit a ticket, then go to the thread and add an attachment.
