remove imported vib/baseline in VUM

Hello,

I imported one vib in the VMware Update Manager (VUM). This vib was a newer version of one driver. However, after many tests we realized we don't need the updated driver. So, I would like to remove this vib/baseline I imported directly in VUM. However, I don't find any method to remove an imported vib/baseline in VUM. Any idea?

Thanks in advance,

Christian
