Import constants to Simulink from Excel file

I am running a simulation in Simulink that requires some constants that change every run. These constants are in an excel file (Uvalues, Area). I would like to import these constants in to a constant block or other for use.

I understand the Simulink from Spreadsheet block treats rows as time which is preventing me from setting constants easily.

I have tried using the MATLAB function block as a source, but it doesn't support xlsread.

Any help is appreciated.

Setup a model callback InitFcn function in which you call a script that loads the xls file using xlsread()
