Allow all vlans between two ports and one on other ports

Hello,

We have an unusual setup and I need some help. I have an ethernet cable coming from outside connected to a switch setup in trunk with 4096 VLANs because we have many VLANs that are automatically setup when a user connect (1VLAN by user) and it is above the 64 VLAN limitation of the switch. Currently this cable is plugged in a WiFi access point that handle all the VLANs but we want to be able to connect to ethernet so we want to place the switch between the acess point and the entry point. We also want to have some ports assigned to specific VLANs on the switch.

We have a working solution using two switches : 1 "dumb one" and the gs308T. It currently works by using the dumb one to split the entry point across the access point and the gs308t and then the gs308t is used to setup the vlans in access mode for the users. What we want to do is get rid of the dumb switch and use only the gs308t. Is this possible ?

In summary, we want to have 4096 VLANs on two port without any managment, and 4 ports with each one VLAN in untagged mode.
