Insert a link to subsytem block in annotation

I'd like to insert a link into annotation text for another block with the same simulation simulink model, I'd reference to link (point) to it.

Is it possible to referenace for block/subsystem from annotation text in simulink, if so - how?

You can simply use an empty subsystem and create a mask to display your annotations. Then, set up an OpenFcn callback. Using hilite_system, you can link it to another block. When you double-click the subsystem, it will navigate you to the linked block.
