Can I have a LOV for display and a LOV for select values in a form ?

Question

My LOV are in table :
lov_return, lov_display, lov_available
To avoid a loss in translating lov_return in lov_display values, I manage a flag, lov_available, Y/N to filter out obsoleted values.
By example, at the beginning of using the application, I have :
LOV_RETURN
LOV_DISPLAY
LOV_AVAILABLE
1
TOP
Y
2
CENTER
Y
3
BOTTOM
Y
And I have records with 1, 2 or 3 in the field corresponding with the LOV.
So far, so good.
Then I want to have a slightly different set of values in my LOV, for new records :
LOV_RETURN
LOV_DISPLAY
LOV_AVAILABLE
1
TOP
Y
2
CENTER
N
3
BOTTOM
Y
4
CENTER-TOP
Y
5
CENTER-BOTTOM
Y
So, when I edit an old record in my form, I want the 2 to be well deciphered into CENTER, and in the SELECT list, I want TOP,BOTTON,CENTER-TOP,CENTER-BOTTOM.
When I assign the dynamic LOV : select lov_display d,lov_return r from lov_table where lov_available = 'Y', to the corresponding field in my FORM, even allowing extra values will not help and will display '2' instead of 'CENTER'.
Is there a way I can manage to show the translated 'CENTER' in the field, and offer a list of values taking in account the 'availability' of the value, other than including the PX_FIELD test in my SQL for the dynamic LOV ?

A common logical problem I encountered back the days of Oracle Forms.
A solution I often see is displaying invalid options with an asterisk, and applying validation to ensure users don't change to invalid selection.
No doubt there are some clever ways to tart this up with jQuery, also.
