Please submit an enhancement request to support, and include details of WHY this would be a good idea. I'm not clear what the driver is for duplicating sheets in drawing.
There are always more requests than there is capacity to implement them, so you need to make a good case to give your request best chance of being chosen.
If you don't want to have to fill in field values manually for each sheet, set the template up to automatically populate fields based on properties from the model. Then most properties can be set for the model and will auto-populate the template fields. OR - Continuation sheets (Sh 2 templates) have no or very few fields that accept manual entry.
To temper expectations - the 'to-do' list for version 28 is already being worked through, it mainly includes PDM related stuff and some items that couldn't be finished for v27. Scope to add anything extra is already very limited.
