Can we generate consolidated documents grouped by the value of one field?

Summary:

Instead of one single consolidated document, can we generate consolidated documents grouped by the value of one field?

Content (required):

We generate consolidated documents based on campaign lines, which means user can select multiple lines and generate one consolidated document. Question: Instead of one single consolidated document, can we generate consolidated documents grouped by the value of one field? For example, user selects 5 lines as below.

Line 1: Field Attribute1 = A

Line 2: Field Attribute1 = B

Line 3: Field Attribute1 = C

Line 4: Field Attribute1 = B

Line 5: Field Attribute1 = A

Based on Attribute1, GTM should automatically generate 3 documents. Line 1 and 5 are in one document. Line 2 and 4 are in the second document. Line 3 is in the third one.
