Each sheet set has a sheet index that you can change to a start value that either reset to 1 or enter a continuation number eg if the previous sheet set ends at 7 you can enter 8 to continue the numbering - in the latter case don't use sheet index of total sheets otherwise it can say things like sheet 20 of 7 etc.
If you want to use a prefix like A: for Plans and B: for Sections etc then add text to your title box that says A: and then add the sheet index smart text to get A:1, A:2 etc
The sheet sets can be ordered using the rank property and then as you create each part of the plan set - set your index to update the sheet numbers as you need them - this is dynamically linked so you can do it just before you print your plan set to PDF etc.
Creating an extra sheet in a plan set for the specs etc- I create a sheet set called Titles and use the Custom Sheet to create the content holder- I copy to sheet to get what Title Box and Borders onto the sheet and then I use Text to place text on the drawings. You can create all your text blocks outside the borders in your template and then drag them into the drawing area as needed. You can copy and paste text from Word or notepad but it will not carry formatting or bullets or numbering etc - that is something we could for sure work on and plug in an open source text editor with at least some formatting functions.
When you move a text block you can use grips to resize it and it can wrap text if you resize the area using grips.
Typical Text create once and reuse by including in your template already structured as you need it. You may find copy and paste from Excel may hold the table layout - inhave not tried that recently and cannot remember what it does
