Is it possible to "duplicate linked" multiple objects at once in Affinity Photo 2 on macOS?

I can select an individual curve and choose "Layer -> Duplicate Linked" to create a copy where changes to the original will be applied to the copy.

Is there any way to do this for more than one curve at once? If I try selecting more than one curve then "Duplicate Linked" is still available in the menu, but if I click it only the first object is duplicated linked; the remaining objects are duplicated in the ordinary way, i.e. not linked.

I think that duplicate linked is limited to one copy "by design", as duplicating e.g. hundreds of objects linked might theoretically cause some "math havoc" under the hood and eventually result in a crash.
But once a layer/object has been duplicated linked, you can continue to duplicate them "regularly" by repeatedly using the standard keyboard shortcut.

Same bug happening on windows btw. I think its counter intuitive, if this is intentional it should not just just duplicate the every selected layer but the first one without linking it to the original. 

Best case would be for it to automatically link each individual layer correctly, or gray out the option when multiple layers are selected, but currently it just seems like it worked (as long as one does not notice the missing chain icons), until a layer is changed

This appears to be a bug so I have logged this with our developers to be improved in the future.
