Lol, nope. Dashboards are awful.
It takes a looooot of work in 2022.2. In 2023.1 (I think) they made it the way you want now. I have yet to test that actually, but I’m preeettty sure I saw that in the controlled release demos. 
Essentially, what you need to do is create a new panel above your grid and add a container, then some columns. Go to the slide out and copy+pasta the fields over to the new grid you made. You can then delete the slide out.********
You will also need to create an event after form_onLoad that calls an event-next widget. The event to call would be whatever one is being called to initialize the slide out fields (you’ll have to do a trace with Dev Tools). Finally, make sure that the grid panel starts collapsed as expanding it is what fires the retrieve. If you leave it expanded, it will attempt to retrieve data after every field you tab out of which could be catastrophic if the unfiltered dataset is large.
****** Huge caveat that I found doing this… If you delete that slide out, it will also delete/remove/hide/whatever the overflow menu that allows you to access App Studio. Super annoying, but not world ending as you can add /designer/pages to the URL before the question mark.
