Date Set Quarter in JDP and Data Picker in Advanced Roadmaps

[Selena Peri]

Kia Ora Team... I have two boards that interlock with one another - one is JDP and the other is JSP.

We have Prem for all our Jira apps.

In a JDP issue the "Start Date", the "date set" is Quarter (e.g. Jan-Mar...)

However, when a create a Teams "Plan", via Advanced Roadmaps - I'm unable to add to my Plan filter "the JDP "Start Date" field - it's unsupported field in Advanced Roadmaps...

Is there a possible way to convert the "Start Date", that as 'date set' as "Quarter" into a Date Picker set, like in JSP?
And... from there, I am able to see it a possible field to add into my Advanced Roadmap Plan?

TIA - appreciate any info...
