Is your Feature Request related to a Problem or Annoyance?

If you want to get to get Color-Number
The only way to achieve that is to:

Make two inputs that record into two different properties.
Then create a view that combines them.
That creates two unnecessary property and unnecessary duplicates stored information.

Describe the Feature you'd like

What i propose is either of three:

Simple option is doubleSelect and doubleMultiSelect types
that has two rows. (It is not exactly clear how multi one should work, and it is probably more logical, that the only difference is that it outputs a list, meaning multiple f them can point to the same property)

OR

Additional value for Option variable, setting it into a separate row.
(such as, for simple select, of "red (option 0)" "- three(option 1)" output will be "red - three" )

OR

A separate group syntax. To merge two or more inputs into one.

Alternatives

Additional Context

No response

The issue names no files, tests, or entry points; begin by locating the input and grouping implementation and its existing tests. Clarify which of the three proposed designs is wanted, then define the expected combined value and verify single- and multi-select behavior.
