How to hit breakpoints when calling functions from embedded command line

Hello, 

when I debug my python program, and I hit a breakpoint, I begin experimenting with the debug console attached to the process. I find this immensely useful. The only issue is that, if I call a function from the debug console, the breakpoints won't be hit; so if I determine that the bug is in a certain function, i need to run the whole program again to be able to step in the function with the debugger. Is there a way to get the behaviour I want? For those of you who worked with MATLAB, you know that it has this functionality and it's pretty handy :)

Thank you!
