### 1.  Data Market: **Access request to several structures**

If you need to request access to several structures, you can now do it from a new screen 'Structures grant requests' in the Data Market module.

You will get a list of structures and clicking on the request button you will add it to your shopping cart. The orange icon means you can request access; green icon means you already have access to the structure; yellow icon means that there is already a request for that structure (either pending to be approved or already approved); blue icon means that the structure is in your shopping cart.
