Currently I'm using the Marugoto textbook (alongside others) so I decided to make an electronic version of the wordlist. Unfortunately, many words are given to us several times - e.g. in lesson 14, then again in lesson 17. But I don't want to copy this into the electronic renshuu version.
When I enter the word-list into a custom lesson, is there an easy way to make sure that word is not already used in another custom lesson?
Or is there a way to split custom lessons? Renshuu immediately tells if the word is already present in the lesson you are currently making... So it might be easier to make one huge custom lesson including several marugoto lessons - and then split it... Splitting custom lessons could be useful in many other ways, I guess, like making separate lessons for verbs, nouns or adjectives from a mixed wordlist...
That functionality does not exist the way you are asking, at least not in a VERY easy way. If you look up a term in the dictionary and click on the + icon next to it, you can see what custom lessons or schedules it has been added to.
If you happen to throw these custom lessons into a study schedule, though, it'll automatically "discard" the duplicates of any terms, so you will not be getting double-hit with terms that appear more than once.
