You can use the central jacking point, but it is best used with great care, i have read that some have used it only for the jack to slip off the jacking point.
I tend to use a couple of blocks of wood/decking cut square, mostly if the car front needs to be raised only them ramps are always your best tool.

Once you have the car up a certain height use some wooden blocks under the wheels.

Take your time and always check everything is going to plan car is lifting ok.

As soon as you can get axle stands under the jacking points or subframe points.
In my case here i was using the higher ramps at the front which i can not drive up with the R40 as the bumper would catch the ramp going up and down, so car was jacked up and the ramps slide under.

Then i raised the back with the trolley jack on the towing hop under the boot area.

This is the final outcome

care and double checking is the right way if you are going to use the front or rear jacking centre points.
Never ever get under the car until you know 100% it is safe and secure, also tell some one you are working under the car also, and to check on you periodically, good excuse for your wife or partner to make you a coffee every 15 minutes or so
PS i would take extra care using a bottle jack, in fact i would not use one.
