Designer | Efficient way to provide a sorted Date as an Input

[walkingbird]

I am trying to create an app where the interface tool would allow the user to input the Month-Year via Multi-Select List Box.

The Date is in yyyy-mm-dd in the source data format which i am converting to Month-Year via Datetimeformat formula.

and using it as a input parameter in the Filter tool in Step 4 ans Step 6 [Annotated in the workflow]

However, i am unable to find a way to show the dates in a sorted manner , i.e Ascending.

Currently they display as below -

However i would like to display them sorted as Ascending like below 

September-2019

October-2019

November-2019

December-2019

January-2021

February-2021

March-2021

If anyone has any other suggestions in regards to date format , that would work as well.

Thank You

Hello,

See attached for a possible solution to this problem. I've modified container 49 with the functionality which you could replicate in the other interface option within your workflow (container 39). 

Hope this helps!
