How Can I Create A Mock Dataset With 10 Groups Of Different Distributions But Equal Means And SDs?

How can I create a mock dataset with 10 groups of different distributions but equal (or very near equal) means and SDs? I preferably want vastly different distributions – normal, bimodal etc. etc. With each group having maybe 50-100 datapoints. Preferably want this as a CSV or something I can easily use in R! Thank you.
