Given a cofinal cardinal function
$h\in {}^{\kappa }\kappa $ for 
$\kappa $ inaccessible, we consider the dominating h-localisation number, that is, the least cardinality of a dominating set of h-slaloms such that every 
$\kappa $-real is localised by a slalom in the dominating set. It was proved in [3] that the dominating localisation numbers can be consistently different for two functions h (the identity function and the power function). We will construct a 
$\kappa ^+$-sized family of functions h and their corresponding localisation numbers, and use a 
${\leq }\kappa $-supported product of a cofinality-preserving forcing to prove that any simultaneous assignment of these localisation numbers to cardinals above 
$\kappa $ is consistent. This answers an open question from [3].
