european_samples.tsv is ambiguous for mapping to application-specific ids

[ddrichel]

The file european_samples.tsv from
https://broad-ukb-sumstats-us-east-1.s3.amazonaws.com/round2/additive-tsvs/european_samples.tsv.bgz
contains plate and well ids, which is supposed to obtain application-specific sample ids from ukb_sqc_v2.txt.
However, the batch id is also required, as plate and well ids are not matching to sample ids unambiguously. For instance, the following entries appear twice in european_samples.tsv:
SMP4_0014640A H04
SMP4_0014502A E05

Overall, the following entries from european_samples.tsv appear twice in ukb_sqc_v2.txt in different batches:
SMP4_0013746A H09
SMP4_0014502A A08
SMP4_0014502A E05
SMP4_0014503A F01
SMP4_0014641A B04
SMP4_0014641A C05
SMP4_0016202A B01
SMP4_0016202A C01
SMP4_0012383A C09
SMP4_0014640A H04

Sex and self-reported British ancestry are not sufficient to resolve the ambiguities for all samples.
Can we still have european_samples.tsv with batch id (e.g. Batch_b043, Batch_b053, ...) added?

Thanks in advance
