Independant naming of index pattern

[BellBiker]

Hello,
the definition of index patterns within KIBANA is restricted to an String which matches to an existing ElasticSearch index. In the case, there exist two date fields within the index it would be helpful to provide a usefull name to the index to easily distinguish the patterns by name.
Lets assume the index is named testmylogs_ with two the datefields @timestamp and myusefulldate and I want to create index patterns which are linked to one of this datefields, it is today only possible to create two index patterns with name1=testmy* linked to @timestamp and name2=testmyl* linked to myusefulldate. If I can provide a free name to the choosen index pattern it is possible to define name1=testmylogs_timestamp and name2=testmylogs_myusefulldate.
Kind regards and Happy New Year
