`cbsodataR::has_substring` equivalent?

[rwaaijman]

I would like to get the data from only the whole year. in cbsodataR I used cbsodataR::has_substring("JJ")
Is this available?

This is not a feature of the SDMX service, so this would be an enhancement. This is namely a feature of the ODATA service on which CBS odata is built
