In FLS, we want to move code, in advanced search relations of elements, to external files (such as a .dll, .xml, etc) and set up Flexi Layout elements to read code (or code blocks) from these external files (.dll is our preferred method).

How can we move code/blocks of code from Flexi Layout to external files and have FLS read the code (not just the variable value, itself)? In FLS help, functions such as ExecuteSQL, ReadFromXML, ReadSingleStringFromXML seem to indicate that FLS has ability to access external sources.

Thank you in advance for your interest.
