Would be nice to have the ability to define global variable for multiple usage. For example: a SFTP patch to a specific folder which is used in multiple scenarios.
-------------------------
WORKAROUND: If you can spare one Data store (https://support.integromat.com/hc/en-us/articles/360006248793-Data-store) you may use it for storing your global variables:
  1. Click on the "Data stores" menu item in the left vertical menu.
  2. Click on the "Add data store" button in the top right corner.
  3. Setup a Data store and the underlying Data structure (see the 1st screenshot).
  4. Click on the "Browse" button of the newly created Data structure.
  5. Add a variable to the Data store (see the 2nd screenshot).
  6. In your scenario, use the "Data store > Get a record" module to obtain the value of the variable (see the 3rd screenshot).
