Putting summary in 8949 for foreign Mutual funds

Hi ,

I have sold a lot of mutual funds and stocks in last year back in my Indian brokerage account.

For Mutual funds 

1) I was investing in SIP (that is a weekly or bi weekly amount in 4-5 mutual funds) ,so number of transactions are very high.

2) I don t have a statement which gives all those transactions in  a file as after becoming a Non resident in India i have to sell them in non demat mode.

3) based on information available at different sources mostly by annual income statement provided by Indian tax authority  ; i created a summary of  Name of security , can t get date of acquisition (but can get if its short term or long term), Date of sale , units, Cost of acquisition  and P and L.

4) Can i put this summary table (created from point 3) in 8949 rather than all the entries ? and will be attaching or keeping my Indian annual income statement from tax authority there (with no date of Buy ; just long term and short term) as proof will that work ?

5) I am thinking of putting date of buy as 1 year 5 days before sale for long term (randomly) and for short term i remember around when i stopped investing in the MF so last day of investment (which is 3 months before sell date) as date of acquisition  for short term.

6) In India Long term is >1 year and short term is <1 year so same as US.

7)Can i put similar summary table for stock entries too ?
