Thanks to both for each option as this opens up new ideas for me.
Looks like within the pushover message composed, I can add the appropriate priority parameter as noted in this post: Pushover Notifications Driver [Slightly Enhanced]
QUOTE From Post:
Prefixes
[S] - Lowest Priority (only available in custom community driver v20221204)
[L] - Low
[N] - Normal
[H] - High
E.g.. Message "[H]This is a test" will send "This is a test" with High Priority to your mobile app.
[E] prefix is now used for emergency notifications and requires the following parameters
retry - how often to resend notification until it is acknowledged (in seconds with a minimum of 30 seconds)
expire - timeout for resending notifications if they are never acknowledged (in seconds with a maximum of 10800)
