Insert view in view (as Global: custom text)

I've made a slideshow-view that displays all images attached to a certain node. Works perfect when displaying the nodes seperately.

Now have created another view that displays selected fields for each node of the same type. I would also like to add the slideshow-view to each of these results.

Tried doing so by adding a Global custom text field with the value [view:slideshow]. Unfortunately only this text is shown in the results, not the slideshow itself.

I have set the insert view filter to be allowed in every input format.

Is there a way to achieve this?

Thanks!
