another useful option is to turn your drawing sheet into a cell and create the cell origin at the origin of the inner panel make sure the inner panel is a shape not 4 lines then you can create the cell with its origin at the origin of the inner panel, then you can always place the sheet cell at any scale and any where you want.. or even move it with move snap to origin and then keyin xy=desired x, desired y ie xy=0,0
enter..
once its placed where you want you can double click on text and edit values and it still stay a cell...
Alternatively create the sheet as a reference file and move it to have its center at 0,0 and always attach the ref file world coincedent then merge it into you dgn if you dont want external refs...
