? RPL/HP-48 - numerical S on a << >> integrand ?

[OlidaBel]

In RPL, is there a way to integrate (S) on a program <<...>> integrand ? I don't think so,
Something like this :
0
1
<<X SIN X SQ - >>
'X'
S
where the legal way to integrate is :
0
1
'SIN(X)-SQ(X)'
'X'
S

a program gives sometimes more flexibility to build a function to integrate.
