Two completed order emails for the two shipping methods

Hi,

we have the following problem.
We have two shipping methods: free in-store pick-up and home delivery. We need to have two completed order emails for the two shipping methods. We need to send a customised completed order email to users who select free in-store pick-up as the shipping method, which should contain a different text and not the tracking id.

looking forward to hearing from you,

Best regards
