Optimize / combine number of watcher

Hello all,
We have created lots of alerts in our cluster and we are unbale to manage those alerts.

Requirement: We need to 2 or more than 2 watcher in one watch.
Like: for index Metrickbeat-* we have 3 alerts for if:

RAM is more than 60% ,
CPU is more than 80 %,
Disk usage more than 90% these 3 alerts are on same index,

Can any one help me to combine these 3 alerts in one watch.

If you need an alert for that as an OR, I suggest you write it as an Elasticsearch query | Kibana Guide [8.1] | Elastic type rule. This way you can do a boolean query that can combine all 3 of those.
