Yes there is, although you'll have to do it yourself. You're probably updating statistics regularly; write a script to monitor stats for the tables you're interested in and save the data. For example:
Code:
create table tablegrowth (
tabname varchar (128) not null,
tstamp timestamp default current timestamp,
card bigint not null,
fpages bigint not null
);
insert into tablegrowth select tabname, current timestamp, card, fpages
from syscat.tables where tabname in (...);
