Yes, I remember the lunchtime repeats of Corrie and Emmerdale - as 623058 states, they stated in September 1993, replacing the (partial) Corrie omnibus that only Granada kept.
These lunchtime repeats weren’t networked (or may have been part-networked) as regions showed them, along with H&A and various quiz shows, at different times in the early afternoon. It seems ludicrous by today’s standards to think of the variation in the early afternoon schedule across the regions, despite the fact they were showing the same episodes of the programmes.
I think this went on until about 96/97? I know the Sunday omnibus was back in some, or all, regions by the late 90s - by then there were 4 episodes a week so I think there were still some weekday repeats too.
Yes, the Corrie repeats were networked but the various regions showed them where they saw fit in the early afternoon - some at one o'clock, some at 1.30. Granada initially dropped the omnibus and showed them as well, but gave them up quite soon after to bring the omnibus back. As before, this only included the Wednesday and Friday episodes, so for quite a while Granada were the only region not repeating the Monday episode at all. The omnibus was in a very prominent slot, mind, for a while it was at 6.30 - opting out of the network showings of things like Dr Quinn Medicine Woman - and I remember it only stopped in this form when the Sunday episode began in November 1996.
This was also the same time Granada were opting out of the daytime screenings of Families and only showing it in omnibus form on Thursday nights. They had some funny ideas.
I know the daytime repeats were still going on at the end of 1995 because on Christmas Day 1995, a Monday, I remember all the regions were showing the previous Friday's Corrie at lunchtime apart from Granada who had to opt-out. I think Granada started showing the daytime repeats when the Sunday one began, but when they were dropped, I think they started the omnibus again, this time showing all the episodes. Certainly in the 1999 Christmas Radio Times, Granada opted out of a networked film to show a Corrie omnibus that, because it included the Christmas Day episodes, took up virtually the whole afternoon.
