Internal linking with e-list

[JaromirSeps]

hello,
I plan to use a feature or technique in a production app and would like to know, if any one of you is using this. I checked, and this is not a documented feature, so I'm worried if it would still work in future versions (this is on 8.1).

Analyst: I have an internal link in the app, where I connect the e-list with some other dimension (organisation structure), which in contributor becomes the e-list. This link takes a checksum into a "check" cube, where there is either zero or a figure. If there is a figure, that's a sign of error. This does not work in analyst, and in order to not get an error message while synchronizing, you have to add at least one item into the elist dlist, that does match the other d-list (organisation structure).

Contributor: On a single e-list item, users will fill numbers in the app, and if they do something wrong, the "check" cube will display some number. The figure is correctly transferred and the e-list is used as a dimension in the link. This however does not display errors from any other e-list items. If an administrator goes to the summary e-list item, he could filter out zero values, and will get on-line overview of errors in all the e-list items.

Does somebody use this or something similar?
Thank you
