How to display VLAN and info from unkown protocol

We use a program which builds ethernet frames which contain 802.1Q info followed by a text to fill the frame. We don't include higher level protocols into the frames. The contents is some informative text or just dummy content. We use the undefined 0x8000 identifier into type field after VLAN bytes.

So a frame shows something like 0x8100 0xa001 0x8000 ... after MAC source address.

Wireshark reads 0x8100 and shows 0xa001 VLAN parameters into Info column (PRI: 5 DEI: 0 ID: 1), afterthat reads 0x800 which is shown into Protocol column (and with "Type: Unkown (0x800)" message in paquet details window) but the following payload is not shown in paquet list window because Info column is occupied by the VLAN info.

I've found a possible Vlan ID column, but not how to show all this information into a new column while kipping the Info one for the text/dummy contents of our frames. How can we do it?

Thank you
