Ability to selectively copy attachments with Regex using Automation

Problem Definition

Currently, it's only possible to copy all attachments using Automation, and is not possible to choose which attachments to copy

Suggested Solution

Allow users to selectively copy attachments using regex, just like the "Delete attachments" action

Workaround

Within the same rule, copy all attachments and then use "Delete attachments" to delete unnecessary attachments using Regex.
