What is the desired functionality that you are missing?
We should offer more flexibility when selecting variable string values. It is fine to allow the user to select values that do not exist yet.
We need to consider the functionality for Dashboard Filters, too.
Which problem are you going to solve with this functionality?
When creating a report in certain situations as a user I already know that a variable will have a certain value even though in the selected process the value was not presented yet. Currently it is not possible to set a variable filter for string values that do not exist yet.
To do
• Allow the addition and selection of a new value
• Once this value becomes a part of the process instance it becomes a part of the list (pre-selected if it had been selected)
