Telegraf inputs.snmp ignore subindex

I am trying to relate data from two different snmp tables. iXftable and cHsrpGrpTable.
Both tables contains information about same network interfaces. Problem is that in cHsrpGrpTable snmp indexes has “tail” added to it and telegraf can not join those tables.

cHsrpGrpStandbyState active(6) Integer
ifName Vlan1501 Octet String

Index 151258589 exists in both tables.
Is it possible somehow to ignore .1501 tail so telegraf would be able to join information from tables?
