Bi-directional ReferencesAny() ?

[MoD]

Hi,
Is there a way to do a bi-directional any mapping?

ReferencesAny(c => c.SharedEntity)
.EntityTypeColumn("ParentType")
.EntityIdentifierColumn("ParentId")
.IdentityType<int>()
.MetaType<string>();

SharedEntity is a class (ie Contact, Company)
Normally, if i used References(), i should add HasMany(x=>
x.SharedEntity) to Contact/Company classes.
What shall i add to Contact/Company to get SharedEntities?

Is it ok to use:

HasMany(x =>
x.SharingRecords).Inverse().Cascade.AllDeleteOrphan().KeyColumn("ParentId").Where("ParentType='Company'");
