"The initial values for a part can be specified using a dedicated compartment labeled initial Values. The initial values over-ride the default values of the properties in the block that types the part."

Let the following example.
I have two blocks : block_A and block_B.
Block_B has a property called "Id" typed as an integer.
I added two parts to block_A: part_A1 and part_A2. These parts are both typed with block_B. In other words, part_A1 and part_A2 are two instances of block_B and are owned by Block_A.

I would like to define a different value of Id for each instance of block_B. So I try to specified a initial value for the property Id of part_A1 and part_A2.
Indeed, in the reference book "A practical guide to SysML", §7.3 p.141 : Quote:

"The initial values for a part can be specified using a dedicated compartment labeled initial Values. The initial values over-ride the default values of the properties in the block that types the part."

Can I specify initial values for a part property with Papyrus?
