How would one write a compare condition to check attachment name?

[Anna Shelley]

Is it possible to configure a compare condition to match only certain file names?  We'd like to create a rule that does the following:

When:  Issue created

If:  Compare two values (If the attachment name is trk12345678910 OR _EXT__T_C__Advisors_Remittance)

Currently I am using for the compare condition: 

First value: {{attachment.filetype}}

Condition: exactly matches regular expression

Regular expression: ^trk\d\d\d\d\d\d\d\d\d$

OR

First value: {{attachment.filetype}}

Condition: exactly matches regular expression

Regular expression: ^_EXT__T_C__Advisors_Remittance$

Then:  Transition the issue to Resolved status.
