I usually put the hotspots on the Master
As James said, the titleblock reduces the usable area. Therefore, the center hotspot is in the middle of the usable area - now in 10 you can use Special Snap points for this, AT LAST! - and from this hotspot, you can go on to create midpoint placeholders for four, eight, any number of frawings to be placed on the sheet.
Excellent one, James! Goes to Tips&Tricks right now!
