[SpecMap] Default work item mask when adding a new item in SpecMap

Make it possible to easily access the Azure DevOps default work item mask when adding a new item. This would help with additional mandatory fields in the work item you want to create from SpecMap. The current behavior restricts us in using the "New item" functionality of SpecMap since we cannot set the fields that are mandatory in our work items and therefore cannot save them. With this behavior we cannot add items from SpecMap at all.

Presumably this should be optional, as you don't want to change the existing behaviour for those users who like it.
