When you want to say : I'd like to bring not all but some parts of a conversation in here or I'd want to retell a conversation , what would the possible expressions be, instead of retell or bring in?
I'd like to bring not all but some parts of a conversation in here
"I'd like to reiterate my previous statement, that …"
"I'd like to repeat my point, that …"
I'd want to retell a conversation ,
If some time had elapsed (e.g. polite reminder)
I would like to recount my previous conversation, where I told you....
I would like to remind you of our previous conversation, where I told you....
Emphatical (However depending on tone of content may be taken as mild or rude)
I already told you, …
I told you, ...
to restate TFD
to state again
Could you please restate that part of X
I also think you use of retell is good too, and to re-visit is oft used.
