Do you want a solution just for maintaining existing products ? i.e. a one off maintenance task or would you like the default description to be created for all new products loaded?
I have a standard description layout for all new products, I then just make changes as required. This results in all products having the same look and feel for the description field.
You can use an SQL script to bulk change all product descriptions to a specific layout then edit each product with specific details
or
You can create a SQL Insert trigger to insert a default description text at the time a new product is created.
If any of the above suits then I can post some examples.
I am not aware of any way to link a single description to multiple products.
