GTM - Parse Google Analytics event_label into separate variables

Question

I work with a vendor that powers email capture experiences on my website. They have a productized solution that pushes events into GA4. Those events are pushed to the datalayer and they don't have the ability to customize the datalayer event.

Here is an example of what they push to GA.

event > "Overlay Impression" event_category > "Overlay Event" event_label "Email Capture | Bottom Bar | All Pages | Need Some Planning"

I want set up triggers in GTM so that I can push these events into Segment and other Analytics platforms.

I'd like to get more granular in those platforms.

Is it possible to parse the event_label string into individual variables?

Desired outcome would be:

Variable Name | Value event | Overlay Impression event_category | Overlay Event overlay_type | Email Capture overlay_deplyoment | Bottom Bar overlay_location | All Pages overlay_copy | Need Some Planning

So far I'm just researching here to see if something similar has been done
