Naming signal in simulink based on workspace variable value.

In simulink, I would like to set the signal names based on the string values contained in a workspace variable.
Example:
In the out.simout field, I get two subfields named "signal1" and "signal2". Instead, I would like them to be named based on the string values contained in a workspace variable.
Is there any solution to this? Thanks!
PS: A simple workaround would be to name manually the two step signals in the Simulink model. Then, the out.simout fields would inherit the names defined in simulink. However, this is not convenient when there are multiple signals.

Don't understand your question. Assume your have a="string1", b="string2" in workspace. You have to associate them with the two blocks in Simulink. In terms of the amout of work, that is the same as labeling the two signal lines as "string1" and "string2".
Are you asking if you could type in a, instead of "string1" in case the string is really long?

Indeed. I would like to use the variable name,e.g. "a" in your example, which contains the string "string 1". That's convenient, especially if e.g. there are many signals bundled together, whose desired names are saved in a variable, e.g.
a = [{'string1', 'string2', 'string3'];

It can't be done like a numerical parameter, where you can type in e.g. pi, instead of 3.1415926535
But it can be done through a script. Do a for-loop for multiple blocks/signal lines.
lh=get_param('PathToBlock','LineHandles');
line=lh.Outport;
set_param(line(1),'Name','ThisIsMySignalName')
or
a = {'string1', 'string2', 'string3'};
set_param(line(1),'Name',a{1});

Thanks for the answer. Your solution sets the name of the Simulink line, but not the name of the signals contained in that line. I would like to change the name of the signals instead.

That is confusing. The name of the line IS the name of the signal. You have to provide an example to clarify it.
