Add acknowledgments and self citations to paper only after the blind review? I am writing a conference paper of the first time, and the conference I am targeting requires anonymized submissions for the peer review. But at the same time, we (as in, my research group) are required to acknowledge the grants and support of our funding agency in all our publications. Plus, I also need to refer to a previous work of our group. 

Is it appropriate for me to leave out the acknowledgements section and the reference to my work while sending the paper for review, but add these details later on if and when the paper gets accepted? 

Is appropriate to add details (the acknowledgments section, for instance) which were not a part of the paper when it went for review?

I could think of this as the only way to satisfy all concerns. Are there better suggestions from more experienced people in academia?
You're required to acknowledge grants and grant agencies in your publications. Right now, all you have is a submission. If and when the submission becomes a publication will be the time to add the grant information in, especially if the venue has a strong anonymization policy for submissions.
