Building CMP packages with only selected content

This request is for AEM Forms specifically Correspondence Management. In Correspondence Management and Interactive Communication you can export letters.

When a user is exporting assets/letters into a CMP file, he normally selects one letter to be packaged. Clicking on "Resolve" shows all related assets to be exported, always together with the data dictionary, even if not updated. In a staged environment, the data dictionary in the lowest environment always contains details which must not be promoted directly. A template author would then like to exclude the unchanged data dictionary from the CMP so as not to promote unwanted development artifacts. The "resolved" asset list just displays the assets but without any option for the user to define which assets have to be included or excluded. This makes a granular export impossible as the user always gets everything. The user cannot export a letter alone on its own.

=>Demand:
Ability to exclude resolved elements from an export package
Export should ideally not export the Data Dictionary.
Have a delete button after the user pressed button "Resolve" to remove selected assets that are not required e.g. data dictionary...
