How to automate deletion of requests for this scenario?

Hi Experts,

Please advice me on following:

<b>Current Scenario:</b> At present full load for cube A is happening which is bringing data for previouscurrentfuture periods also.

<b>Required :</b> We need to restrict data loading daily as number of records hve become huge.

So approach is fixed previous periods data i.e

1)Load previous periods data.Do not load daily previous periods.

2)Load current period daily with delete overlapping requests.

3)Load future periods and delete those requests daily to avoid duplicacy of data.

Now deletion of current period can be taken care with setting in infopackage, but What about future periods setting? <b>How to delete those requests which are bringing data for future periods.?</b>

We need to automate this fully without manual intervention for future.

Thanks in advance,
