Preventing my SE reusing sms filenames.

Posted by Goggen
When I delete a SMS message my SE K750 will reuse that filename. Is there a way to prevent that.

E.g.
I have currently 5 sms messages

....\sm_FFFFFFFF_00030.sms
....\sm_FFFFFFFF_00031.sms
....\sm_FFFFFFFF_00032.sms
....\sm_FFFFFFFF_00033.sms
....\sm_FFFFFFFF_00034.sms

Then I delete

....\sm_FFFFFFFF_00032.sms

Then I send 2 new sms. My directory will now show

....\sm_FFFFFFFF_00030.sms
....\sm_FFFFFFFF_00031.sms
....\sm_FFFFFFFF_00032.sms ---- new sms - reused filename
....\sm_FFFFFFFF_00033.sms
....\sm_FFFFFFFF_00034.sms
....\sm_FFFFFFFF_00035.sms

What I want is to prevent my phone to reuse sm_FFFFFFFF_00032.sms filename, so after sending 2 new sms I would like to have:

....\sm_FFFFFFFF_00030.sms
....\sm_FFFFFFFF_00031.sms

....\sm_FFFFFFFF_00033.sms
....\sm_FFFFFFFF_00034.sms
....\sm_FFFFFFFF_00035.sms
....\sm_FFFFFFFF_00036.sms

Any configuration files that could do the trick???
I'm using FAR and sepf...
