 * Add list with structure similar to PIRs, in which specific data updates by FSCC can be listed (along with their reason and a "change_date"). These can then be applied in a way similar to updated values in the checked PIRs.
 * Convert script into a function, in which you can choose the survey form (so_som, so_pfh, s1_som, s1_pfh) and the variable to calculate stocks from. Different methodological decisions (e.g. about internal gap-filling opportunities) should be changeable via function input variables. List these important methodological variables and their options. A file with this methodological information should be exported as metadata in the output.
