Question: Can I make define_external functions available across multiple workbooks?

Question:Can I make define_external functions available across multiple workbooks?

I have functions using define_external to call a .dll  In uploaded file "dll_test.mw" I'm showing one such function.  Immediately after defining the function I call it and it works.  There are a lot more similarly defined functions and once defined in the worksheet they are working as hoped. 

My question is can I make the functions avaliable across multiple worksheets somehow?  google ai suggested using "read" but in uploaded file "read and load test.mw" you can see that it's not working for me.  using read I get an error I don't understand and using load doesn't return an error but it also doesn't result in an executable KinAddCurveData function.

Any help would be very appreciated.
