New version device support

I’d like to add support for a new version of the device. But I have a problem, Ray-2 and Ray-1 devices no index, so it won’t work in yaml
eg snmpget -v1 -c public 10.133.16.243 .1.3.6.1.4.1.33555.1.3.2.1.0 iso.3.6.1.4.1.33555.1.3.2.1 = INTEGER: -548
but Ray-3 is already ok snmpget -v1 -c public 10.133.49.99 .1.3.6.1.4.1.33555.1.3.2.1.0 iso.3.6.1.4.1.33555.1.3.2.1.0 = INTEGER: -505
is there any possibility to have all versions?
