Using SLA instead of Priority in new tickets

Is there a way to use the SLA dropdown instead of Priority when creating new tickets (client and agent side)? I do not see SLA as a dynamic field to select as an option for the Ticket Details form. Could this be added w/o too much issue?

For background, I have created SLA plans (see image) that define both priority and time frame for various issue types (mainly projects and tickets right now but that will be expanded) that work better than Priority for defining time frames, which response/resolution time is something we pull regular reports on just to get an idea of efficiency. So being able to select this at ticket creation time in place of Priority would serve the Priority purpose much better (unless osTicket adds the ability to assign priority levels and time frames associated with them).

Thanks for any info provided.
