Hello @EasilyAmused,
Thanks a lot for loving Enpass and sharing your experience.
Sharing of fields among various items is indeed a good feature and can really save a lot of time when you have to keep multiple items with same credentials like various Microsoft and Google services accounts or there could be various bank accounts having multiple debit cards but same login credentials. We have noted it in our roadmap to introduce in any of future versions.
In fact, all they belong to same account, so for now in Enpass you can create a single item with multiple URL fields (one for each service), with a must-have field with login URL for autofilling i.e accounts.google.com for Google services as login to all their services is done through same page.
Keep using Enpass with all your suggestions and feedback to help us in overall improvement of Enpass.
Cheers!
