RealTerm: Serial/TCP Terminal

Using the command line (actually, setting the target line in the shortcut's properties), is there a way to specify a SEND file ('Dump File to Port') without having it automatically begin sending?

I'm using this command:
'SENDFILE=C:\bin\8kbas.bin '
which does indeed load the file into the Dump File box. But it immediately begins sending that file. I need to do a few preliminary manual commands first, before clicking on the SEND FILE button. Is there a command something like 'LoadSendFileButDon'tDumpYet' that I'm just not seeing? Any work-arounds that you can think of?

Thanks for your replies.
