Thread Subject: Any workaround to use workspace structures in Simulink for xPC Matlab Function block?

I am trying to work a way to take structures generated from my M files that are not always the same format and use them for calculations inside an Matlab Embedded Function Block in Simulink for use with xPC Target. Currently, I am using from workspace blocks to break down the structure variable by variable but this restricts me to knowing the format of the struct initially. I saw a function on the file exchange called v2struct which converts a struct into a variable array and vice versa but it's not compatible with simulink.

Has anyone tackled this type of problem and have been successful?
