multi-type data storage in a Variant

I have a test app I am writing and it uses a lot of dates. The data gets displayed in a listbox and I am attempting to store the record id and a object. I am formatting the date data to make it more easily readable for users but I still need the date object for later manipulation. This is going to be stored in the listbox row’s rowTag

Can I store a dictionary in the Rowtag?

You can store anything you’d like.
