Has any worked with setting rules using multiple keywords without creating a separate filter for every keyword?

I want an email about the in classroom display to create a ticket using a specific ticket type and issue and assign a specific agent to it. However, teacher don’t only use one specific word or phrase to refer to in-classroom technology. We have ViewSonic ViewBoards or: display, smartboard, viewboard, touchscreen, etc.

I would like set a rule that says if any form of the words above are used in the subject or body of the email to then set specific parameters to the ticket: assign ticket type, assign to specific agent, etc.

Currently, it seems I have to create a filter for every work or phrase possibly used.

For example: we used Zendesk before this and had this ability.

Thanks!
