equivalent to TCSTART.btm for TCMD?

I use tcc.exe about 99.99% of the time. But for the infrequent time when I want to start up TCMD, I noticed that it doesn't seem to run my TCSTART.btm file like a TCC window does. Is this expected? If not, is there an equivalent (say, TCMD.btm)? Note: I'm using TCC 16.03.55 x64 Windows 8.1 [Version 6.3.19043].
