Is there any way to split a line in Simulink, so that I can insert blocks with more than siso? (also, sometimes the drag and drop to insert a siso block doesnt work)
Splitting the line would preserve all junctions before and after.
I only found a workaround, that you can see in the gif.

Right-click and hold the line you want to split, and drag it to extend the newly created branch. See the following video demonstration (no audio): Video Link
Here, I'm holding the right-click on the line and dragging it to create a new branch. Drag it to the inport of your desired block, and release it to connect the line to the block.
You can include a manual switch to toggle between the outputs of the different blocks, to choose which will be used in the model simulation.

Hello @Moritz Ischebeck, I understood your question now, thanks for clarifying. A working solution to this has been posted by @Yoshi Minagawa.

Hi Moritz,
I don't know how to delete only the part of the signal line as you mentioned. But you can do the similar thing by this method.
Please see the gif. You can remove the block itself by dragging mouse with pressing shift key. That enable you to keep the line shape after removing block.
I hope it will help

yeah, thats the same workaround I found aswell, as shown in my gif.
I wish, there would be an option like "crop Lines inside rectangle" next to "Auto-route Lines"
