If you submit a request using the resource request feature, you also have the option to indicate a preference for a resource. However, in the resource board in the planning board, it is not visible for that resource that a request has been submitted for this person. This can lead to duplicate requests or incorrect interpretation that the resource is available.
The resource board must make it clear that the resource in question has been requested. The usual red-shaded bookings can remain in the project board, where, for example, the description states which resource has been specified as a preference.
