Escalation Chains for bank holidays vs standard weeks

Hi LogicMonitor community,

We are fairly new to the product, just looking to see if anyone had any advice for handling Escalation Chains when it comes to Bank Holiday weekends.

We currently have escalation chains created for our teams to handle automated call-outs for our critical devices/checks during standard weekends and outside of core hours. However with Bank Holiday weekends requiring the need to operate the same process on Friday/Monday's depending on the specific weekend, we'd need to ensure those additional days does are covered too. 

The obvious solution we've come up with is to create a Bank Holiday On-call escalation chain for each of the teams where we can be flexible and amend the days we'd want to be called out on, then swap out that escalation chain to any alert rules which required it. This would work, although considering we've got multiple teams configured with on-call escalation chains within LogicMonitor as well as many alert rules using them, this is a manual process we'd need to keep on top of before/after every bank holiday, which leaves some room for human error of course.

Has anyone implemented something similar and have any advice they would be willing to share? I can't imagine we would be the first customers to come across this scenario.

Thanks in advance!
