Further development of the DLE admin 10.3

Hello. You have such a feature in DLE 10.3
I got the wagon unpublished news, which was filled at once. Naturally, all with the old date.

Need:
1 – allocate the necessary news
2 - in admin panel new item batch change the date or whatever is to the right or bottom button is not important. Tarkay. prompts start date and end date. Put.
The script counts the number of days and news. The news divides into days, receives an integer and each cycle marks the date of the news cycle and random time.

What you need: Tired of the daily go to sites and update. I want to allocate 50 news, put the date in the order and he may publish in 5 pieces a day. 10 days will come again, etc.

Important:
full automatic is unacceptable. I have to point news that you want to change the date
The script should not be allowed to change the date on the published news, i.e. it is only unpublished. Don't need to skip, the script first checks whether the list of selected published news
