Sampling/Publishing Interval parameters to be part of Data Selection description

When configuring the AVEVA Adapters in general, we would find more convenient to be able to define the ‘Sampling Interval’ and 'Publishing Interval' parameters inside the ‘Data Selection’ configuration per each data stream. For instance, when describing the data addressing of the OPC UA items to collect inside the ‘Data Selection’ configuration, we would see additional ‘Sampling Interval’ and 'Publishing Interval' params to describe it.

Currently the ‘Sampling Interval’ and 'Publishing Interval' (or anciently called ‘scan class’) are now defined at the ‘Client Settings’ under the ‘Component’ section of the configuration, for all ‘Data Selection’ described. This effectively forces us to create several ‘Components’ for each different ‘Sampling/Publishing' intervals we wish to create, hence making this somewhat more cumbersome to manage.

We have to define in average five 'Components' and we need to make sure that the proper data stream is located under the corresponding Sampling Interval, so prone to errors.

Eventually it would be good to be compliant with the OPC UA standard (https://reference.opcfoundation.org/v104/Core/docs/Part4/5.12.1/) where a negative value in the 'Sampling Interval' parameter indicates that "the default sampling interval defined by the publishing interval of the subscription is requested.”
