Tvheadend

Hi like to find out how to configure my monoblock lnb which has two adapters configured as DiSEqC 1.1 / 2.1.
tvheadend 3.4.27 detects my Digital Devices DVB-S2 PCI-e card and made two tuners available known as " DDSTV090x Multistandard ".

Yet I like to find out how to configure my two satellites, which is Thor+Intelsat 0,8W and Sirius ( astra ) on 4,9E.
I noticed under "Satellite Config" entries can be added, so I created PortA (switchport0) and PortB (1) and set lnb types to universal, assuming this configures which part of lnb to use for Sirius and Thor/Intelsat. Once this is set up I can simply add satellites from the selection list at: " Add DVB Network by location " so sats should scan in one by one?

Hope one can guide me a little to set this up properly.
Thanks in advance
