 It is possible to request both the integrated and single cycle plots by the same Check.

+Please remember to use `"location" : "local"` in such case.
 
 In asynchronous QC, the moving window plots will appear in the intermediate QC file in the directory `mw` and will be uploaded to QCDB to `<task_name>/mw`.
 When testing, please make sure to let DPL know that it has to run in Grid mode, so that QC can compute object validity based on timestamps in the data:
