[Therion] map offset, why not scrap offset allowed

The Therion book 5.3.11 says, for map syntax, pg 31; if you refer to map, you can specify offset at which this sub-map will be displayed together with preview type of its original position. Syntax is following: <map reference> [<offset X> <offset Y> <units>] <above/below/none> If I specify a scrap to be offset instead of a map, no error is generated, but the scrap is not offset. Is it likely that one day soon we might be able to offset scraps, or is there a good reason why this should not be possible or desirable? If not, then perhaps a warning message should be generated to say that the scrap could not be generated. Regards
