The Things Uno: using two sliders over LoraWAN

I have added two sliders to The Things Uno device
I find when I have moved both sliders I only receive LoraWAN downlink data on one slider in response to the next uplink
e.g. sample console output
– LOOP Temperature = 23.68 *C
Pressure = 102166.83 Pa
Sending: mac tx uncnf 1 016700EC027327E8
Successful transmission
– LOOP Temperature = 23.71 *C
Pressure = 102170.38 Pa
Sending: mac tx uncnf 1 016700ED027327E9
Successful transmission. Received 0733F4FF << received channel 7 value 133.00

– LOOP Temperature = 23.73 *C
Pressure = 102169.21 Pa
Sending: mac tx uncnf 1 016700ED027327E8
Successful transmission. Received 060BB8FF << received channel 6 value 30.00

in the above even though I moved both sliders I only receive data from the last one moved (channel 7 in first case channel 6 in second)

is there any way to get the position of both sliders?

Cayenne triggers unitary command. hence you receive only one downlink at a time.

scenario:
hundreds of units with a number of system control parameters which may to be configured remotely using buttons, sliders, etc (or locally using Android BLE)
units would connect using LoraWAN or a GSM modem once a day to uplink sensor data and downlink any parameters updated since the previous uplink
I can uplink sensor data OK using LoraWAN or a GSM modem - the problem is how to downlink updated parameters (say up to six) - can it be done?
