Hide Prefix + Single Selection

[TimB]

Is there any possibility to combine dimensions with a hidden prefix with single selection?

I can hide my dimension _dim with "Set HidePrefix = '_';"  but then i can't set a single selection on this field.

If you mean always one selected value, you can set that without the hideprefix, then set the hideprefix. The setting will persist, at least on April 2019 Patch 1 when I tested.

You can eventually expose that field using a filter pane, for example, with "_FieldName" in the expression.
