FM SWN_CREATE_SHORTCUT. Can i_parameter use Not Equal

I am using FM  SWN_CREATE_SHORTCUT  to send mail to users with a shortcut to SAP transactions.

I have used these shortcuts to successfully start transactions and pass input screen values with i_parameter.

However, I have so far only used = sign.  for example:

CONCATENATE

     'S_MATNR-LOW=XYZ123;'

     'S_MATNR-HIGH=XYZ999;'

     INTO gv_parameter

My question is, can I use other comparison types like NE(not equal) to exclude certain values ?
