Faster way to construct signals in Signal Builder

The standard method of constructing signals is using the 'Signal Builder' block in Simulink. I need to update the signals quite frequently and I would like to know if there's a faster way to do it - something along the lines of writing the numbers in the command window or spreadsheet values. The dragging part in the builder is very slow for me.

Use the signalbuilder function

Look at this link How can I make changes to the Signal Builder block from the command line in Simulink 6.2 (R14SP2)?
