Slack integration with values of variables in Alert summary

Hi LM Community,

We're putting LM into production and moving away from Zabbix.

This is what we see in slack channel using the built-in Slack-LM integration.

Here System Uptime Uptime Seconds shows, but we want the summary alert to show value in summary instead of having to click Full Alert details, especially with mutiple on-call staff using Slack on phones, we want to minimize interaction like clicking. LM support offered to create hooks, but then we loose a lot of other functionality. He offered to add this to a feature request, wondering if someone already ran into this and figured out a workaround.

Thanks a lot for any help on this!
