shortcut groups with multicenter groups?

I'd like to make a Cp shortcut group.  I tried defining it this way:

Cp  *.c1cccc1 |m:0:1.2.3.4.5|   1

However, when I draw Cp→Ta on the canvas, the multicenter group is no longer present:

[Ta]*.c1cccc1 |C:1.0|

Is there any way I can fix this problem?  If not, can you make it a feature request?

Hi Bob,

From 6.0 we will support cxsmiles in the import of our abbreviated group format instead of SMILES and all of it's features will be available in abbrevgroup format too. Note that the export of these groups with cxsmiles is planned to 6.1 only.

Best regeards,

Peter

So in Marvin 6.0 I will be able to define Cp and draw structures with it, but if I export the structures to MRV, the Cp will automatically be ungrouped.  Correct?  And this flaw will be fixed in 6.1?

No, exporting to MRV will be fine but you will have to create the

Cp  *.c1cccc1 |m:0:1.2.3.4.5|   1

string manually, you can't create it with molconvert or save it from Marvin. From 6.1 you this will be available if the molecule is saved as Chemaxon Abbreviation.

Oh, that's fine, I would create it manually anyway.
