Attribute Link - Filter Types - SubString

I am trying to filter out a substring from a hex payload.

Here is the string…

DE081311AABBCCDDAB9300230AE63F47E457

The format of the payload is…

I’m trying to extract the last 8 characters (“3F47E457”), convert from hex to a number, and assign to a custom attribute.

Is it possible to do this with Atrribute Links?
