How to combine multiple requests?

Question

Yii

Hello. There is such a request

Description::find()->select(['LEFT(`name`, 1) AS name', 'LEFT(`name_en`, 1) AS name_en'])->distinct()->all()

but distinct does not work here and stupidly throws out everything that is in the database.
1) how to make it possible to make a selection as I indicated, i.e. take the first letter without duplication in two columns at once, it would be great if it is possible to make the selection case -insensitive
2) I put the first column in name, the second in name_en, if I make the second one also put in name

Description::find()->select(['LEFT(`name`, 1) AS name', 'LEFT(`name_en`, 1) AS name'])->distinct()->all()

then it overwrites the first one, can you somehow make a selection in one variable?
ps made two requests,

Description::find()->select(['LEFT(`name`, 1) AS name'])->distinct()->all()
Description::find()->select(['LEFT(`name_en`, 1) AS name_en'])->distinct()->all()

and put it in one array, so everything works, but is it still possible to somehow put everything in one request?)
