ISBAT Implementing ability to select a custom post type instead of regular posts in Posts block

[gdandrija]

Is your feature request related to a problem? Please describe.

No, I want to see if other custom post types can be used by Posts block in one of the latest updates

Describe the solution you'd like

Usage of the Posts block by a custom post type, ideally a selection box where you could select a custom post instead of a regular post type

Describe alternatives you've considered

The only alternative would be picking a dedicated category which is not always applicable

Additional context/screenshots

If there is a technical way of implementing this functionality, it should be at least considered

The selection box may be placed here for an example: https://i.imgur.com/t9estaH.png
