Automatically repeat custom insert block command

I have created a customized right click menu to insert various blocks into my drawings.  How can I have the command in DraftSight to repeat automatically without having to right click and select the block each time?

In AutoCAD LT 2006, I use the following command  *^C^C-insert;spl.dwg;\\;;;

This will insert the spl.dwg block as many times as I want until I select Esc (or cancel).  With this command, I only have to specify the insertion point each time.  I do not have to specify any scale or angle.

In DraftSight, I tried a similar custom command *^C^C-INSERTBLOCK C:\\AUTOCAD\\BLOCKS\\SPL.DWG;\\;;; and *^C^C-INSERT C:\\AUTOCAD\\BLOCKS\\SPL.DWG;\\;;; I have also tried numerous variations of these two commands.

After adding the spl.dwg block successfully the first time, the DraftSight Command line asks to Specify block name>>, Specify destination>>, Specify x scale>>, Specify y scale>>, Specify z scale>>, Specify angle>>  I have to answer all 5 command questions every time I insert the same block.

I have settled for the following command in  ^C^C-insert c:\\autocad\\blocks\\spl.dwg;\\;;;\\;^C

This inserts the spl.dwg block once in the drawing and then cancels the command.  However, to repeat the command, I have to right click and select the block every time.
