The introduction of the tag tool in ADT 2006 was wonderful for placing single-scale tags. But, since this forces annotation scaling, presents a dilemma when trying to insert scale-dependent tags, which want to be inserted at x- and y-scale factors of 1 and have multiple view blocks, each scaled appropriately for the intended scale. The workarounds would have been to set your drawing scale and annotation plot size such that the resultant scale factor is 1 (which works, but is cumbersome) or to create an old-fashioned AEC Content file and making a tag from that. That also works, but since the source file for the schedule content is not in the AEC Content folder structure, might have lead to the creation of a second source file for Property Set Definitions within that folder structure, to support the scale-dependent tags - OR - to moving the source file to a folder in the AEC Content folder structure, breaking all existing tags that reference that source file.
By using a Windows shortcut to include the schedule source file's folder in the AEC Content folder structure, you can have your cake and eat it too (or leave the source file where it is and still make AEC Content that references it). This blog article shows the details of how to do this, for anyone who may be interested.
