Question: Load File Name for Simscape Multibody File Solid from Workspace

Is there a way to specify the File Name parameter, that is, the file path of the geometry in the Simscape Multibody File Solid block with a MATLAB workspace variable?   It seems to me that only direct paths can be specified. Callbacks and masks are also only accessible to a limited extent. Does anyone have an idea how to implement this or is it just not possible?   Such a function would be very handy if you want to run simulations with different File Solids on one model.   I am grateful for any suggestion.

    As Charlotte mentioned, this solved the problem:
     
    I did it by executing these commands in the MATLAB command menu. First get the handle for your current block (or whatever block. e.g. 'myModel/File Solid')
     
    a = gcbh
     
    Look at the list of parameters by doing this
     
    get(a)
     
    Choose the parameter you want to change, e.g. ExtGeomFileName for the File Solid block and set it to what you want
    set_param(a, 'ExtGeomFileName', filename)
     
    where filename is the variable in your workspace
