To achieve the desirable workflow, please consider using the option 'Promote' from when editing the mask of the Subsystem or Block, see the following figure accordingly,

A detailed description of the latter workflow can be found in the following documentation page,

In this way, variables that are used within the Subsystem or Block can be accessed and edited in the custom mask even when they are located inside the linked Data Dictionary.
