Adding dashes within a specific field

[mcoile]

I'm new to Alteryx Designer and I have what I hope is a simple question. I have a data field that is all numbers (but formatted as a V_String) and I want to convert this to add dashes to match the FAA Airworthiness Directive numbering scheme.

Examples: I wish for the string "890503" to become "89-05-03", and "20200803" to become "2020-08-03".

Any help is appreciated, thanks!

I used a Reverse String Function to do it.

Dont know if you have other cases other than the two sample you have given.
