[FR] Movable Items In Between Grids (Pages)

### Description

I have recently attempted to create a client lead space within Appflowy with 3 different Grids.


Hopefully the attachment is visible that I just uploaded.

Anyways - I found that I was unable to move an item between different categories. For example that would be from - New List to Hopeful List.
I have tried for several days to find a workaround but I haven't been successful.

### Impact

I think a fix to this issue would be a game-changer. If people like me had this option then there would be no need to use any other program as a database. People could move over their accounts from Obsidian - Trello - and even Click Up. This was my objective ( I was almost there).

### Additional Context

As for the $ part of it.. I know there are a lot of people out there that would be more than happy to spend some money to have a fully working database, so that they could eliminate other applications. I definitely 100% would spend the money to have this working as well. The simple fact that my data is on my own hard drive is value enough to make Appflowy my go-to App.

If you could make this happen I know it would mean so much for so many people, even if it is a paid option.
