Is there a way to consume custom UI5 library from SAP Business Application Studio?

Hi experts,

In Web IDE, we had this nice feature where you can reference a custom library sitting in the same workspace as the consumer app.

We would set "Use my workspace first" in run configurations, and this enabled running the app on WebIDE, referencing the custom library.

In Business Application Studio, can we do the same sort of thing?

I thought of using a separate approuter, but it didn't work.

Regards,

Mio
