No tilemap asset option in blueprints

My tilemaps do not show up under any of the available options. Also, for sprites, sounds, and so on – they are labeled as “assets”.

The issue is that I want to dynamically change the tilemap which a blueprint component uses by use of the SELECT node – but there is no tilemap asset option like there is for other assets.

As a temporary solution I might add components to a blueprint for all tilemaps I need, collect their reference in an array, hide all of them or disable, then only enable the one on a specific index. Not the prettiest but perhaps the easiest work-around.
