Getting Data In

Using Custom option for ingesting VPC flow logs into Splunk

Hello there, 

We are looking to use the Custom option to send vpc flow log data to Splunk Cloud. Previously we were using the default set of fields. There's a need to ingest additional fields without using the "all fields" option in order to save on data ingest. 
The issue appears to be with the Regex where the add-on cannot mix and match field names, rather it needs to be in a particular order otherwise the data is not parsed properly.

Default Format:
${version} ${account-id} ${interface-id} ${srcaddr} ${dstaddr} ${srcport} ${dstport} ${protocol} ${packets} ${bytes} ${start} ${end} ${action} ${log-status}

Custom Format
${version} ${account-id} ${vpc-id} ${subnet-id} ${interface-id} ${instance-id} ${flow-direction} ${srcaddr} ${dstaddr} ${srcport} ${dstport} ${pkt-srcaddr} ${pkt-dstaddr} ${protocol} ${packets} ${bytes} ${start} ${end} ${action} ${log-status}

This is preventing us from being able to include additional fields that can be useful to our team, without ingesting everything. Has anyone else encountered this problem before?
